Application filed February 4, 1924. 'Serial No. 690,466.

B nomical, effective and highly eflicicnt device that is adapted toreceive the vapor and boiling liquid from the overflow pipe of theradiator and to condense the vapor, thereby permitting the liquid toflow back into ll) the water circulating system. The scope of myinvention extends to whatever construction may be defined by'or includedwithin the terms or language of the appended 'claims- In the drawing:

Figure is a side elevation of my improved condenser shown applied to amotor;

Figure 2 illustrates a somewhat diagrammatic view of my improvedcondenser, and Figure 3 is a view in perspective partially broken away,illustrating another embodiment of my invention.

My invention in the form or "embodiment shown in the drawing and brieflydescribed, comprises a condenser 10, which is; as shown in Figure 1',supported from the upper portion of the cylinder block by means of an Iangular bent strip 11, which is bolted to the upper portion ofthecylinder block. 1 prefernto mount my improved condenser approximatelymidway between the fan and the engine block.

lhe condenser 10 is provided with an upper compartment 12, and a lowercompartment 13 which is relatively shorter than the upper compartment.

'Ihecompartments 12 and 13 are connected together by a plurality ofsuitabl spaced apart and vertlcal tubes '14, whic are either expandedinto their roper position in the compartments, sol ered or securedthereto in any other desired manner.

. This construction, of course, affords easy communication and freecirculation between the compartments 12 and 13. For very readilyassisting the cooling of i the vertical tubes 14, I have provided a plu-1 provide a threaded nipple 16 and a threaded mpple 17 is likewiseprovided on the lower end of the lower compartment 13 for a purposehereinafter described;

An overflow pipe 19 is provided in the upper portion of the radiator inthe usual manner and is extended downwardly and connecting with theupper end ofa threeway valve 20. The valve 20 is provided with sideopenings which are adapted to communicate with, the pipes 21 and 22.When the opening in the valve communicates with the pipe 21, as isclearly shown in Figure 2, it will be readily seen that the vapor fromwithin the upper portion of the radiator will be drawn downwardlythrough the pipes 19 and 21 into the upperor con-.

densing compartment 12.

Should it ever be desired to cut out the condenser 10, as for repairs,the valve may 'will. of course, permit the vapor to pass out totheatmosphere in the usual manner instead of conserving it. 4

23 indicates the return pipe which is con nected at the bottom of thelower com artment 13 by means of the threaded nipp e 17, from whichpoint it extends downwardly, connecting with the main return water pipe24, which, of course, directs the water to the engine from the lower endof the radiator.

To revent the water from the pipe 24 to be orced up into the tube 23, 1provide a check valve as indicated at 25 in Figure 1. In the condenserillustrated in Figure 3,

l have provided a substantially rectangular ing tube 33 is fastenedtherein in a suite manner.

Threaded nipples 34 and 35 are located in the upper and lower ends ofthe rectan lar casing or condenser 30 and prefera ly in diametricallyopposite corners, so that the vapor entering the nipple 34 will befully-- condensed before reaching the nipple 35.

It will thus be readily seen that the cool air entering thetube 33through its lar e end 31 will readily condense the vapors wit in b:hecondenser 30 and surrounding the tu It is to 'be nude that thestructural elements are susceptible to such constructions and changes asfully within the scope .or terms of the appended claims.

I claim:

1. In combination with an internal combustion engine radiator havingwater circulating pipes, a condenser, comprising an upper and lowercompartment, condensing means, interposed therebetween, an overflow tubeleading from the radiator, a three-way valve connected thereto, afeeding tube'leading from the three-way valve and communicating with theup er compartment, a second tube diametrica 1y opposite said feedingtube, a condensate tube leadingvfrom the lower compartment to one ofsaid water circulating pipes and a check valve located in saidcondensate tube.

2. In a cooling system for an internal combustion engine, thecombination with a radiator of a condenser supported in rear of theradiator, means for by-passing the overflow from the upper header of theradiator to the condenser, said means being operable to cut-out thecondenser at will, and means for directing the condensate from thecondenser to' the cooling system beyond the radiator.

3. In a cooling system for an internal combustion engine,,thecombination with a radiator of a condenser arranged in the rear of andopen to the full cooling influences aflecting the radiator, a feedingpipe connected with the radiator overflow pipe and leading into thecondenser, means whereby the overflow of the radiator may be directed tothe condenser at will, and a condensate pipe leading from the condenserto the cooling system.

In testimony whereof I aflix my signature.
